Osteo Arthritis Knee
Conditions
Keywords
Platelet rich plasma, bone marrow, stem cell
Brief summary
Previous clinical trials have demonstrated the human body's own healing and regenerative cells can relieve the pain of arthritis. Bone marrow contains stem cells which can change into cells of various different tissue types, while platelet rich plasma contains growth factors. Both techniques have been shown to relieve pain and with this study the Investigators wish to compare the two treatments.
Detailed description
Participants will be randomized into two groups. Concentrated Bone Marrow Aspirate (BMAC) or Platelet-Rich Plasma (PRP). BMAC subjects will have bone marrow aspirated from the subjects iliac crests and the cellular rich portion will be concentrated and subsequently injected into the subjects' symptomatic knee. BMAC patients will also have a venous whole blood drawn from the antecubital vein to simulate a PRP procedure. PRP subjects will have the same venous blood draw from the antecubital vein with subsequent platelet concentration. The resulting PRP will be injected into the symptomatic knee. PRP subjects will also undergo a bone marrow aspiration from the iliac crest to simulate the BMAC procedure. Follow-up at 1 week, 6 weeks, 6 months, and 12 months after injection, with repeat radiographs at 12 months.
Interventions
